Proximity

Proximity probe systems measure axial or radial shaft motion for machine protection applications. Metrix offers an array of probes, cables and drivers that are interchangeable with competitive probe systems from Bently Nevada and others. Replace individual components with our ProxMatch™ color coding system or purchase a complete Digital Proximity System consisting of a probe, extension cable and a MX2033 Driver or a MX2034 Transmitter.





Setpoint

Condition Monitoring

The SETPOINT family of products includes a rack-based machinery protection platform and online condition monitoring software powered by PI®  that deliver complete API-670 compliance.

 

Visit www.metrixsetpoint.com for more detailed information.

    Metrix proximity vibration transmitters are compatible with Bently Nevada Series 3300, 7200, and 3000 probes and cables as well as our own probes and cables. The flexible Metrix MX2034 Transmitter can be reconfigured to handle any of these probe / cable combinations.


    5516 Signal Conditiones

    Signal Conditioners

    Metrix proximity signal conditioners are used with existing drivers. They power the driver and scale the 4-20 mA output.


    Proximity Accessories

    Accessories

    A full line of accessories for mounting probes and WP or EP enclosures for drivers, transmitters and signal conditioners.


     


    Horizontal Pumps

     

    A pump is a device that moves a gas or liquid from one area to another. This can be done by accelerating the liquid using centrifugal forces (centrifugal/rotodynamic pumps) or by grabbing a certain amount of liquid and physically pushing it towards where it needs to go (positive displacement pumps). Pumps are perhaps the most widely used mechanical devices and their designs vary as much as their applications.

     

    Centrifugal Pump Monitoring Options




    440 Switch with External Sensor
    Provides local contacts as well as 4-20mA output for interface with PLC. Sensor is located on pump while440 switch is located in a more electronic friendly environment.
     

    SA6200A and 5535
    Provides 4-20mA output for interface with a PLC / DCS. Dynamic signal is available from front panel for vibration analysis purposes. Provides options for custom filters, local display/indication, or galvanic isolation.

     

     

     

     

    ST5484E ST5491E
    The ST5484E provides for the simplest installation available. Since it’s a loop-powered device, only two wires are needed for full operation. The ST5484E is connected directly to a PLC / DCS. Optional filtering and dynamic outputs are available. The ST5491E has a local indicator.

     

     

     

     

    Special Case - Large Vertical Pumps
    Large pump applications, such as the one shown above, require a more thorough monitoring scheme than smaller applications. 

    Metrix provides a vibration sensor for all bearings, an impact sensor to detect cavitations, and a Datawatch monitor. The Datawatch monitors all vibration and temperature readings and compares them to pre-programmed setpoints in order to change the state of alarm and danger relay outputs.

     

     

     

    Special Case - Pumps with Journal Bearings
    Journal bearings use a layer of oil to isolate the shaft from the bearing. Therefore, the shaft is actually floating on a cushion of oil and has no contact with any other metal. Because of the oil layer, a vibration signal produced by the shaft does not have a path to travel to the machine casing. That means that a seismic sensor placed on the case of the pump cannot properly sense what is going on with the shaft.

    This makes it necessary to use proximity sensors to detect shaft faults. A proximity probe mounts through the case of the machine and senses the position of the shaft relative to the probe tip. The pump casing holds the probe steady so that any movement in the shaft will cause the proximity probe / transmitter to give an indication. This type of measurement is termed “relative” because the shaft movement is being measured in relation to the machine casing.

     

     

     

     


     



    Seismic

    Seismic vibration instrumentation is used to measure structural vibration on bearing housings, piping, machinery housings, and machine support structures.  It is particularly suitable for machinery with rolling-element bearings. These types of bearings will generally transmit both shaft-and bearing-related vibration to the outside of the machine where it can be detected by seismic measurements.





    Sensors

    Sensors

    Seismic sensors provide a dynamic AC signal output in mV/g or mV/in/sec.  Devices with this type of output are generally intended for connection to a stand-alone vibration monitoring system rather than general automation and control instrumentation like a PLC or DCS.  Metrix offers seismic sensors with a wide variety operating temperatures, frequency responses, scale factors, case materials, connector types, mounting options, and hazardous area approvals.


    Transmitters

    Transmitters

    Seismic transmitters provide a 4-20mA DC signal output proportional to the vibration amplitude, and are ideal for applications where a PLC, DCS, or other automation system will be used instead of a stand-alone vibration monitor. Metrix offers seismic transmitters with a wide variety operating temperatures, frequency responses, scale factors, case materials, connector types, mounting options, and hazardous area approvals.

     


    Seismic Signal Conditioner

    Signal Conditioners

    Seismic signal conditioners are designed to accept an input from (and provide power to) a seismic sensor. They convert the signal to a proportional 4-20mA DC signal that can be used as an input to process control instrumentation such as a PLC or DCS.  They provide additional convenience features such as optional displays, BNC connectors for access to the dynamic sensor signal, and bandpass filtering.  Metrix offers seismic signal conditioners that can accept either acceleration or velocity sensors, and are available with or without an integral display.


    Accessories

    Accessories

    Seismic accessories include bushings, mounting adapters, junction boxes, conduit fittings, cable assemblies, and other items used when installing sensors, transmitters, and signal conditioners. These accessories provide enviromental protection from dust, moisture, and corrosion, robust mechanical protection from the rigors of industrial use, and facilitate professional installation where wiring can be properly terminated, routed, and labeled.
